entrycompletion: Ensure transient_for is set before showing window

Browse Source 
gtk_entry_set_completion() (and _gtk_entry_completion_connect underneath)
may happen when the entry has no toplevel yet. This window acts as the
"parent" for subsurface windows on wayland, and is indispensable to create
its backing wl_subsurface, so this resulted in non-visible popups there.
Fix this by ensuring transient_for is set before showing the popup.
